Abstract
Epoxidic compounds are produced by treating with peracetic acid an ester or ether of an unsaturated alcohol of the general formula <FORM:0823180/IV (a)/1> in which R represents hydrogen or an alkyl radical and R1 an alkyl radical. Suitable alcohols for the formation of the ether and ester starting materials are those in which R represents hydrogen or methyl, and R1 is methyl, ethyl or propyl. They may be obtained by dehydration of the corresponding 1.3-diols or by partial hydrogenation of unsaturated 2-alkyl branched aldehyde. By pyrolysis of the diacetates which are formed by acetylation of the 2-alkyl branched 1,3-diols (readily accessible by aldol condensation and subsequent hydrogenation) there are obtained the mono-acetates of unsaturated 2-alkyl branched alcohols of the above formula. These acetates may be readily re-esterified especially with methyl esters. After saponification, they may be esterified with monobasic or polybasic acids or acid anhydrides, for example acetic acid, adipic acid, phthalic acid, epoxytetrahydrophthalic acid, phosphoric acid, mono- or di-alkylphosphoric acid or sulphonic acids to esters, or reacted with alcohols, glycols, polyglycols, thioglycols, diethanolamine or diphenylolpropane to ethers. These ethers and esters are then epoxidized by dripping into peracetic acid in glacial acetic acid or acetone at 30 DEG to 35 DEG C. and then stirring for 5 to 6 hours at the same temperature.
